Overview
I am a cancer surgeon who specializes in treating patients with pre-cancerous and cancerous conditions of the pancreas, liver, bile ducts, stomach, and adrenal glands. I initially trained and practiced at Walter Reed Army Medical Center in Washington, D.C. During this time, I served one year on a forward surgical team in Iraq. Following this service, I practiced for 13 years as a surgical oncologist at Memorial Sloan Kettering Cancer Center in New York. In 2018, I joined the faculty at Duke University and now serve as the chief of surgical oncology for Duke Health. I enjoy getting to know my patients and delivering the highest quality of cancer care. I am dedicated not only to treating and curing your cancer, but also providing you with the highest quality of life. Operations for cancers within the abdomen are a serious undertaking, and I am committed to making sure that they are performed with the highest level of expertise.

Duke Ambulatory Surgery Center
I specialize in the surgical management of benign and malignant diseases of the gastrointestinal tract (GI) tract. Specifically trained in laparoscopic resection of inflammatory bowel disease and colorectal cancer, I perform the full range of colorectal operations, including reconstructive operations, such as ileal pouches. My clinical, research, and administrative efforts are all focused on implementing perioperative care practices that ensure best patient outcomes. Bridging specialties to best care for GI surgery patients, I particularly enjoy combined cases. For instance, I regularly operate with the pediatric surgery team on younger patients with IBD or pelvic cancer. Until my exposure to surgery in medical school, I thought I wanted the patient-doctor relationship well-known to primary care. With experience, however, I realized this relationship was possible in the practice of surgery. Colorectal surgery allows me the privilege of long-term relationships with a great variety of patients; close relationships with my colleagues; and administrative positions that promote the best care.

Her top areas of expertise are Colorectal Cancer, Familial Colorectal Cancer, Crohn's Disease, Hernia Surgery, and Hemorrhoidectomy.
